I've recently traded a cup with someone and I'm wondering if there is any risk involved in that in terms of cleanliness? I'm new to cups and don't completely understand everything quite yet. Thank you to anyone who is able to help answer my question! :)

Slight risk
A lot of menstrual companies don't recommend using a cup that has already been used by another person however if you sterilise it properly then it should be okay. Companies also don't encourage it because of hygiene issues.
Personally I wouldn't do it just because of my own personal feelings about swapping cups (I just don't like the idea of doing it) but as long as you take precautions you should be okay

Re: Slight risk
Most of the reason they say that is, likely, that a user buying a cup secondhand takes away the profit the company could have made from selling that user a new cup. So of course they will say don't buy secondhand. That said, I will boil any cup I receive from a previous owner and boil any cup I am selling to a new owner before sending (despite the fact that I am free of such creepy crawlies, it's just good practice)

Both of my cups I've gotten used. Upon arrival, I washed them with unscented soap, rinsed really well, wiped them down with rubbing alcohol and called it a day.

If I understand correctly... and please, someone with better medical knowledge correct me if I'm wrong... really "bad" microbes (such as HIV or Hep and others) cannot live for long outside of a host. The contact would have to be fresh and direct for them to transfer successfully. And because cups are made of non-porous materials, contaminants of all types stay on the surface. Washing with soap and hot water, boiling, sloshing in alcohol or a 10% bleach solution or other chemical means (and then washing/rinsing thoroughly) will probably eliminate any threat of contagion.

There is also a sense of honor and personal responsibility that if a seller suspects that there is something amiss medically, that they will not pass their cup along to someone else.

Personal opinion: We are at greater risk from bad judgement in our choice of casual hook-ups than from 2nd hand cups.

Kuradi: I agree with you.

For the sake of education: The Hepatitis C virus can survive outside the body at room temperature, on environmental surfaces, for at least 16 hours but no longer than 4 days. (from the CDC website)

HIV is fragile. It can survive weeks outside the body but conditions (Temperature, pH) have to be just right.

HIV is sensitive to high temperatures but not to extreme cold. Experiments have shown that HIV is killed by heat, but temperatures over 60°C are needed to achieve reliable killing of HIV. (From aidsmap.com).

So I think the bottom line here is that if you boil the cup it will eliminate HIV and Hepatitis viruses. Other STDS--the bacterial ones like Chlamydia and Gonorrhea don't survive long outside the body (minutes to hours), and boiling would eliminate them too.

Viruses freak me out. They aren't really living, but that's a whole other discussion.

I think you're more likely to get a cold this winter than anything bad from a second hand cup--especially if you boil it.

I do think there is very low risk and would not discourage passing on cups. I do think though that yeast infections can survive on the surface of a cup through boiling and sterilising. I think that is why cup companies state not to reuse

Hydrogen peroxide kills yeast, though (at least, it does whenever I get one), and I know most users will soak their cups in it just to get bloodstains off, if nothing else.
